Pick walk

Pick walk on CVs and hulls

The term 'pick walk' is used for the process of stepping from one CV or hull to the next using the Ctrl + Arrow keys. For example if you are shaping a curve by moving CVs, instead of selecting the next CV with the mouse, you can use the Ctrl+arrow keys to select it, and then move it directly.

Pick walk is also useful for stepping through CVs in order to check if there is any unwanted 'zig-zagging'.

To use pick walk, select one or more CVs, edit points or hulls, and then use the Ctrl + Arrow Keys to step backwards and forwards.

For a curve:

  • Ctrl + Up arrow or Right arrow - Increasing U
  • Ctrl + Down arrow or Left arrow - Decreasing U

For a surface:

  • Ctrl + Right arrow - Increasing U
  • Ctrl + Left arrow - Decreasing U
  • Ctrl + Up arrow - Increasing V
  • Ctrl + Down arrow - Decreasing V

In practice, most users just experiment with the arrow keys until they find the right direction.

Pick walk in the Object Lister (Object View)

  • Shift + Up arrow key moves up one level in the node hierarchy.
  • Shift + Down arrow key moves down one level in the node hierarchy.

Pick walk in the SBD window

  • Shift + Up arrow key moves up one level in the SBD hierarchy and selects the whole surface.
  • Shift + Down arrow Key goes back down the hierarchy, eventually to the first CV on the object (U=0, V=0).
  • Alt + Right or Left arrow moves the selected nodes left or right in the SBD
Note: Currently these don't work if the SBD window or Object Lister are the active window. Click in a modeling window to allow the pick walk keys to work in the SBD window or Object Lister.
